<u>Area of a rectangle</u>
Given a rectangle of width W and length L, its area is calculated as follows:

The area of the given rectangle is 48 cm^2, and the length is three times the width, thus:
L = 3W
Substituting into the formula of the area:


Simplifying:

Solving:


The width is 4 cm. Find the length:
L=3W=3*4= 12
The length is 12 cm.
